After a modest presence in the cross tracks at the beginning of the project and V2 entry stage world in 2009, Aprilia continues its adventure in the universe of cross by introducing the MY 2010 in the MXV 450, which will be piloted by the World MX1 Josh Coppins.
Unique design, essential, unique off-road in Noale is the only player in its class to use a twin-cylinder engine 450, defined “45.2″: Already known for his victories in all categories of the Supermoto World and for good performances enduro, the compact power unit is characterized by the MXV angle of 77 ° between the cylinders, integrated in the crankcase and are lined by wetlands.
BIG BANG OR SCREAMER
The innovation introduced with the MXV 450 compared to enduro and supermoto models through the possibility of set timing, So as to satisfy the maximum demands of the pilots in terms of delivery: in a few hours can go by timing the “Big Bang” – set series from the house – the more powerful but less “exploitable” timing to regular bursts known as the “Screamer”.
A very interesting “feature”, adds the ability to adjust the delivery of the engine through two different maps provided by the injection system Dell’Orto, based on throttle bodies 38 mm. A map “full power” be used in conditions of good grip and a map soft for disbursement sweeter in difficult conditions. Just one click to get the power right at the right time.
Definitely interesting the opportunities offered by the system Service and Programming, Which allow you to update the maps via download from a website dedicated to Aprilia, do the calibration – “fine line” – the throttle position sensor (TPS) and change, within limits, the carburetion of the engine and the ignition advance to adapt the engine to operate your driving style.
FINEST MATERIALS
Despite double the number of cylinders, the engine weighs just Aprilia more than a single cylinder traditional. This was made possible by the use of materials such as titanium for the valves, aluminum silicon for the crankcase, magnesium covers, as well as the distribution solutions shaft head Instead of the classic twin-cam, which helped to contain weights and dimensions. Unlike sisters enduro and motard, electric motor would not start MXV. Goodwill is Foot and lowers the weight to a minimum.
JOINT FRAME AND SWINGARM Hydroformed
From a cycling point of view, the perimeter frame has specific quotas for cross and was developed hand in hand with the engine: Is characterized by the mixed structure, which allows the upper lattice of steel tubes coupled to interference with side plates molded aluminum. A project that draws from the experience base of SXV and RXV but differing widely in cycling and shares in the form of the swing arm, which was designed to be as light and flexible as possible with arms achieved through process idroforming.
As for the front suspension, the Aprilia engineers have relied on a fork Kayaba upside-down with stems 48 mm: This is an pluriregolabile, designed to offer maximum opportunity to sew him the bike like the Sachs rear monoshock, also adjustable, which works through “mediation” of a progressive linkage. Nissin floating callipers and 270 mm front disc Wave, combined with a 240 mm rear disc “bite” from a single-piston floating caliper, but make up the brake system.
TANK Redraw
Other differences from the models also concern the enduro and motard fuel tankNow designed to centralize the masses as much as possible and minimize the overall dimensions, but also the platforms, which have a new location. Also changes the design of air box, Which is located in front of the bike, leaving space to fuel tank that extends over the shock. The air box also allows the housing of the throttle bodies raised and facilitates Replacement filter.
Inside the air box is also the control unit and all components of the electrical system. The exhaust system, with underseat silencer Double outlet, is completely made of titanium (collectors and muffler). The electrical system is “minimal”, with no battery (batteryless system) and fully integrated into the filter box. Among the peculiarities, finally, even the two-tone saddle with specific step “median”, Designed to contain the best driver in the early stages of acceleration.
